This inspection warns about nil-safe chained calls which could be replaced with safe navigation
operator usage.
A group of chained calls is likely to represent subsequent checks for <code>nil</code> in every call component, like:
<pre><code>
if u && u.profile && u.profile.thumbnails && u.profile.thumbnails.large
  # do something...
end
</code></pre>
This expression could be replaced with:
<pre><code>
if u&.profile&.thumbnails&.large
  # do something...
end
</code></pre>
